Improvement in horse-powers

IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 118,292, dated August 22, 1871.

. in arranging and combining parts s0 as to economize space and secure a more desirable proportion and size in such of the working parts as suffer the more rapid Wear and deterioration. My invention consists, in part, in arranging the lilieshaft upon an incline to the plane of the revolving wheels, as exhibited in Fig. 3, by the structure and arrangement of certain parts in manner 5 and for thepurposes hereinafter set forth. Again,

my invention consists in overlapping the two crown-wheels in connection with a peculiarlyconstructed foot or bridge to support the masterwhcel, the inner bearing for the line-shaft, and two transverse rollers, as and for the purposes specified and explained hereinafter.

In the drawing, Figure 1 represents a plan of the machine, all parts being in position; Fig. 2, plan of the two crown-wheels and the two pinions that mesh into them 5 Fig. 3, longitudinal vertical section, presenting manner of arranging the crown-wheels, pinions, and line-shaft; Fig. 4, the central support for the line-shaft and antifriction rollers detached and on an enlarged scale 5 Fig. 5, the same opposite side.

A, the master-wheel; B, one of the crownwheels, lying lower than the inner end of the line-shaft and facing upward 5 O, shaft of crownwheel B 5 l), a pinion on upper end of shaft O, which meshes into the master-wheel A; E, another' crown-wheel, lying higher than the inner end of line-shaft and facing downward; F, shaft of crown-wheel E 5 G, a pinion plyin g into master-wheel A5 H, the line-shaft; I, a pinion iixed upon the inner end of said line-shaft and engaging with crown-wheel E 5 J, a pinion on said lineshaft, near to pinion I, and provided for adjustability, as and for reasons explained elsewhere in this specication; K, reaches of the runninggear of the wagon part of the apparatus, serving also as a bed upon 4which the main working parts of the power rest and are supported; L, other parts of the frame supporting the masterwheel; M, the wheels on which the machine is transported; N, the axles for these wheels; O, the sweeps, to which the teams are attached 5 P, a cross-bar, resting upon the longitudinal bars L, and itself' supporting in conjunction with reaches K the part Q, in which is the block i", which provides the bearing for the inner end of the line-shaft, upon which are the anti-friction conical rollers s s, and in the upper end of which is the bearing u for the journal of master-wheel A. For form and manner of attaching this supporting-piece Q see Figs. 4 and 5.

In arrangement I place the crown-wheels overlapping one the other, in order to be able to enlarge the pinions D and G to a proper size for durability and to work Well in meshing into master-wheel A, and all without enlarging the said master-wheel, and thus economizing space.

As all the parts must be arranged with relation to the size of the master-wheel I, in order that all the gears shall properly mesh, not slip, nor work too close, lit one of the pinions on the inner end of the line-shaft for adjustment on said shaft, and this is necessary for the reason of the variations in djiferent samples of the crownwheels and master wheels, although always molded from the saine patterns-a matter which. those who are accustomed to fitting large gearwheels fully understand.

To fasten pinion J I have represented a hey, fu, but any other suitable means may be adopted.

The arrangement of the line-shaft upon an ineline, as it leads away from the working parts, is to 4provide for the horses stepping over it without the necessity of a universal joint to provide an offset or dropping down, as some have heretofore made use of, or the bridging up for `the horses to walk up overan exceedingly unsatis factory way adopted by others.

l do not claim in this invention two crownwheels, one lying on a higher plane than the other, one` facing upward and the other downward, with a pinion Working into each.

What I do claim as my invention, and desire to secure by Letters Patent, is

l. The crown-wheels B and E, when overlapping one the other, and operating the two pnto this specification in the presence of two subions I J, one Xed and the other adjustable, as soribing Witnesses. and ior the purposes specified. ISAAC STARR.

2. The line-shaft H, when provided with Xed pinion I and adjustable pinion J, and arranged Witnesses: to lie inoiining, as speoied and set forth. R. H. MARSH,

In testimony whereof I have signed my name D. C. COLBY.
